This is a very unique and interesting amber necklace. The amber pieces are flat and measure approximately 1/8" think. They are strung together on two parallel strands of yellow thread. All of the pieces are different sizes, shapes, and colors and no two are alike. The two largest center pieces measure 1 1/4" X 3/4". The length is difficult to measure because the necklace can not be laid out straight but has a curve to it. The best I could come up with is 21.50" in length. Excellent condition.
